    (54) Liquid piston internal combustion engine


    (57) A liquid piston internal combustion engine comprises two upright combustion chambers (1) interconnected at their lower ends by a U passage (2) containing a quantity of liquid (3) which is movable between the combustion chambers (1) in alternate cycles of operation of the combustion chambers (1). Each combustion chamber (1) has a head (4) closing the top thereof, means (5) for admitting air, means (6) for admitting fuel for combustion and means (7) for exhausting the products of combustion from the chamber (1). In the form illustrated, the quantity of liquid (3) is used itself as a piston. In an alternative, the quantity of liquid is used to link together hydraulically solid pistons movable in the combustion chambers.
